Might want to use paint remover and a metal scraper. **Q: Are these good for wood?** A: They are actually VERY good on wood. Much faster than most sanders. You have to have a steady hand though. **Q: can this be used for sanding a jon boat?** A: I wouldn't recommend this for sanding a Jon boat as too much pressure with a grinder could penetrate the skin of the boat. **Q: what grit on these discs would be best to remove light rust and smooth paint on body of a 10 wheel dump truck** A: I would think 80 grit would do best for the light work you’re describing. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Price, Reliable *by J***R on April 14, 2026* Very happy with these - I use them to sharpen my zero turn blades - they do a really good job and offer lots of life. ### ⭐⭐⭐⭐⭐ Good Product and Value *by M***R on March 30, 2026* I bought these to sharpen lawnmower blades.
